The supervolcano lurking under Yellowstone National Park may not have resulted from a rising plume of hot rock from the planet’s depths as previously suggested.
New simulations of North America’s underside reveal that the mantle plume blamed for powering the Yellowstone supervolcano is in fact cut off from the...

When you see a bad moon rising, expect an ever-so-slightly wetter day. The lunar gravitational pull imperceptibly boosts rainfall when the moon is on the horizon and somewhat reduces rainfall when the moon is overhead or on the opposite side of the Earth, a new analysis of global rainfall concludes.
The cause is the...

Rumbling earthquakes could reveal faraway weak spots in Earth’s crust.
Following a 2012 earthquake that rattled Costa Rica, researchers noticed that the quake fractured underground rock tens of kilometers from its epicenter. Before the quake, that fractured region had already been weakened by pressurized fluids mixed in with...
North Korea sent political shock waves around the world on January 6 when it claimed to have carried out a successful test of a hydrogen bomb, which, if true, would be a substantially more powerful and sophisticated class of weaponry than the country’s previous efforts. The underground test generated a...
Olivia Buchanan loved to ski. She grew up in the high country of Colorado and, at age 23, was studying snow science at Montana State University in Bozeman, hoping to make a career in the mountains she adored. On January 6, 2015, however, the snow turned against her. In the backcountry terrain of Colorado’s San Juan Mountains, Buchanan’s skis cut through the powder, freeing a slab of hard older...
In the sky above eastern Antarctica, airborne ice crystals sculpt the sun’s rays into a ring.
This phenomenon, called a 22-degree halo, is the result of sunlight passing through tiny, six-sided ice cylinders in high-altitude clouds. The crystals act like prisms, bending incoming light 22 degrees off course. Millions of crystals at various orientations can cast a full circle of light...
For Earth’s early inhabitants, living in a bubble was a good thing.
Pockets of gas trapped along ancient shorelines gave microbes a cozy place to call home about 3.2 billion years ago, scientists suggest December 4 in Geology. Such a snug hideout could have shielded microbes from ultraviolet...
